The Pella® Impervia® line combines style with durability in fiberglass windows and patio doors that, as the name infers, are impervious to nearly all types of weather.
Impervia’s toughness comes from Duracast®, our special fiberglass composite. It’s one of the strongest and most reliable materials in the market for fiberglass windows and patio doors1. Duracast stands up to temperatures from extreme heat to subzero cold, making Pella Impervia windows and exterior doors exceptional for all seasons.
The superior insulating properties of our fiberglass replacement windows and patio doors enhance your home’s livability and help reduce energy use. Optional foam-insulating frames could be included on these ENERGY STAR®-certified windows and patio doors.
Pella Impervia windows and sliding patio doors are delivered prefinished with a factory powder-coat finish that stays looking great for the long haul—inside and out—with little maintenance. With an array of colors to explore, you’ll find windows and patio doors to match your home’s look, inside and out. Our environmentally friendly paint process essentially removes toxic chemicals, helping the air inside your house stay chemical-free.
Pella Impervia brings quality that you can count on and beauty that stands out. And to top things off, they are secured by our limited warranty—one of the best in the industry.2
